2020 MAZDA MODEL 6 radiator

Rocking the Vehicle
WA R N I N G
Do not spin the wheels at more than 56
km/h (35 mph), and do not allow anyone
to stand behind a wheel when pushing the
vehicle:
When the vehicle is stuck, spinning the
wheels at high speed is dangerous. The
spinning tire could overheat and explode.
This could cause serious injuries.
CAUTION
Too much rocking may cause engine
overheating, transaxle failure, and tire
damage.
If you must rock the vehicle to free it from
snow, sand or mud, depress the accelerator
slightly and slowly move the shift lever/
selector lever from 1 (D) to R position.
Winter Driving
Carry emergency gear, including tire
chains, window scraper, flares, a small
shovel, jumper cables, and a small bag of
sand or salt.
Ask an Authorized Mazda Dealer to check
the following:
Have the proper ratio of antifreeze in the
radiator.
Refer to Engine Coolant on page 6-29.
Inspect the battery and its cables. Cold
reduces battery capacity.
Use an engine oil appropriate for the
lowest ambient temperatures that the
vehicle will be driven in (page 6-25).
Inspect the ignition system for damage
and loose connections.
Use washer fluid made with
antifreeze―but do not use engine
coolant antifreeze for washer fluid (page
6-32).
NOTE
Remove snow before driving. Snow left
on the windshield is dangerous as it
could obstruct vision.
Do not apply excessive force to a
window scraper when removing ice or
frozen snow on the mirror glass and
windshield.
Never use warm or hot water for
removing snow or ice from windows and
mirrors as it could result in the glass
cracking.

Windshield Wipers andWa s h e r
The ignition must be switched ON to use
the wipers.
WA R N I N G
Use only windshield washer fluid or plain
water in the reservoir:
Using radiator antifreeze as washer fluid is
dangerous. If sprayed on the windshield, it
will dirty the windshield, affect your
visibility, and could result in an accident.
Only use windshield washer fluid mixed
with anti-freeze protection in freezing
weather conditions:
Using windshield washer fluid without
anti-freeze protection in freezing weather
conditions is dangerous as it could freeze
on the windshield and block your vision
which could cause an accident. In addition,
make sure the windshield is sufficiently
warmed using the defroster before
spraying the washer fluid.
NOTE
If the windshield wipers are operated
under cold weather conditions or during
snowfall, they could stop due to
accumulated snow on the windshield. If
the windshield wipers stop due to
accumulated snow on the windshield, park
the vehicle in a safe place, turn the wiper
switch off, and then remove the
accumulated snow. If the wiper switch is
turned to another position other than OFF,
the wipers will operate. If the wipers do
not operate even though the wiper switch
is turned to a position other than OFF,
consult an Authorized Mazda Dealer as
soon as possible.

NOTE
(SKYACTIV-D 2.2)
When inspecting the engine oil level,
pull out the dipstick straight without
twisting. In addition, when inserting
the dipstick, always insert it without
twisting so that the “X” mark faces the
front of the vehicle.
5. Pull it out again and examine the level. The level is normal if it is between the
MIN and MAX marks.
If it is near or below MIN, add enough
oil to bring the level to MAX.
CAUTION
Do not overfill the engine oil. This may
cause engine damage.
6. Make sure the O-ring on the dipstick is positioned properly before reinserting
the dipstick.
7. Reinsert the dipstick fully.
NOTE
(SKYACTIV-D 2.2)
Inspect the engine oil level
periodically. When inspecting the
engine oil, if the engine oil level is
exceeds the “X” mark on the dipstick,
replace the engine oil. This should be
done by an Authorized Mazda Dealer.
When replacing the engine oil, inspect
the oil level using the oil dipstick and
refill so that the engine oil level is
within the rang e between MIN and
MAX as shown in the figure.

Engine Coolant
▼ Inspecting Coolant Level
WA R N I N G
Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS HOT:
A hot engine is dangerous. If the engine has
been running, parts of the engine
compartment can become very hot. You
could be burned. Carefully inspect the
engine coolant in the coolant reservoir, but
do not open it.
Pull over to a safe location, then switch
the ignition off and make sure the fan is
not running before attempting to work
near the cooling fan:
Working near the cooling fan when it is
running is dangerous. The fan could
continue running indefinitely even if the
engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not remove either cooling
system cap when the engine and radiator
are hot:
When the engine and radiator are hot,
scalding coolant and steam may shoot out
under pressure and cause serious injury.

NOTE
Changing the coolant should be done by
an Authorized Mazda Dealer.
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year―at the beginning of the
winter season―and before traveling where
temperatures may drop below freezing.

Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.

The coolant should be at full in the
radiator and between the F and L marks on
the coolant reservoir when the engine is
cool.
SKYACTIV-G 2.5

SKYACTIV-G 2.5T

SKYACTIV-D 2.2

If it is at or near L, add enough coolant to
the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to F.
Securely tighten the c oolant reservoir tank
cap after adding coolant.

CAUTION
Radiator coolant will damage paint.
Rinse it off quickly if spilled.
 If the “FL22” mark is shown on or near
the cooling system cap, use of FL-22 is
recommended when replacing engine
coolant. Using engine coolant other than
FL-22 may cause serious damage to the
engine and cooling system.

If the coolant reservoir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.
Brake/Clutch Fluid
▼ Inspecting Brake/Clutch Fluid Level
WA R N I N G
If the brake/clutch fluid level is low, have
the brakes inspected:
A low brake/clutch
fluid level is dangerous.
A low level could indicate brake lining wear
or a brake system leak which could cause
the brakes to fail and lead to an accident.
The brakes and clutch draw fluid from the
same reservoir.
Inspect the fluid level in the reservoir
regularly. It should be kept between the
MAX and MIN lines.
The level norm ally drops with
accumulated distance, a condition
associated with wear of brake and clutch
linings. If it is excessively low, have the
brake/clutch system inspected by an
Authorized Mazda Dealer.
